I have an ul with several li.
I use this id on the ul.
#list { margin-right: auto; margin-left: auto; width:500px; color:black; background: -webkit-l
It might sound weird but:
replace transparent with rgba (0,0,0,0.0001)
transparent
rgba (0,0,0,0.0001)
It doesn't work with rgba (0,0,0,0)
rgba (0,0,0,0)
